The tank A embodying my invention is of the usual type constructed ofheavy: sheet metal as steel, and lined with glass enamel being providedatits lower end witha discharge pipe B and at itsvupper end with aflange G. D indicates the outer shell 015; sheet metal constituting thejacket and spaced from the exterior of the vessel A a sulficientdistance to affordspace ior receiving heating or E indicates the bottomof this outer shell which maybe constructed in one piece with the side,but is preferably a separate structure welded or otherwise securedthereto, and having in its bottom a dis- 7 charge pipe F.

In jacketed or double walled containers of this general type the heatingor cooling fluid is sometimes introduced into the exterior chamber byspray pipes or jets discharging against the side of the interior tankand considerable diiliculty has been encountered in properly sealing theupper part oi the jacket to the tank and in properly positionthroughout25, 1922. 1 Serial no. 590,304,;

ingand securing the spray pipes in position. Inorder to, overcome these"objections and produce awstructurewhich is highly efficient and may bemade economically, 1 form the closure for the upper endof the tankjacket of :a tubular ringer conduit G, the inner side of which is firmlyunited to the inner vessel A near its top and the outerside of which isfirmly united to the upper edge of the jacket 1) so that this ring notonly constitutes a sealer forthejacket but a conduit for the fluid tobeapplied to the space. between them. The lower or inner surface of thering is pro vided with the vspray apertures H, arranged in groups tospray the liquidover the sides otthe inner tank, as shown inFigur'esLand The outer side of the ring is provided with iarger apertures J inthimhles welded or sejcunedjto the pipeand' providedwith plugs K,- oneof these" openings. being adjacent each groupof spray apertures H'so asto permit access to the latter forcleaning, when the closing plugs orcaps fK threaded 'intotheapergenously j welding the parts, although theymight with some degree of success be other wise secured as by brazing,but I prefer the abled to first weld the inner surface of the ringsealer to the tank A before its interior.

surface is enameled, and afterwards weld its exterior to the edge of thejacket without liability of cracking the enameled surface, as mighthappen if subjected to extreme heat. This construction'also enables meto i'acilitate the construction of the container because the sealerconduit rings can be made in quantities from ordinary welded steeltubing, then pressed or flattened somewhat, as shown, .to widen them andproducenarrower edges which can be more readily welded to the tank .andjacket, and these rings thus prepared can be readily fitted and securedto standard sized tanks [1. The sealer-rings are also provided with afitting L for the attachmentof the pipe conveying fluid to the interior.When in use the fluid introduced in the ring conduit is delivereddownwardly from the apertures H in the form of fine jets or sprays uponpractically the whole exterior surface of the tank A, thereby heating orcooling the contents quickly and in the event that former method as theparts are then substantlally integral and moreover I am enthe jetopenings should become clogged each group can be cleaned by removing theplugs K.

In making these tanks the following method is found advanta eous:

First the tank body A is completed in the usual manner; then thepreviously prepared sealer ring is electrically or autogenously weldedto the exterior thereof at the top, then the enamelling glass-mix orsimilar material is applied to the interior of the tank, and this ssuitably melted in the usual manner by placing the tank in a furnace.After removal and cooling, the jacket D which, has its upper edgebeveled slightly to fit approximately the lower edge of the ring sealer(Jr, is welded to the sealer and the operation is completed.

\Vhile I much prefer to weld the sealer ring to the body of the vesseland the shell by the use of electricity or by an oxy-acetylene blowpipe, as I find this produces a much better connection, the parts couldbe otherwise welded or even brazed, and I have used the term united inthe claims to distinguish either of these forms of connection from suchdetachable connections as might require packing of some nature to make atight joint. The welded or brazed joints serve to make the wholestructure practically integral preventing leakage.

I claim as my invention:

1. A container comprising a metallic vessel, a metallic jacket or shellsurrounding and spaced from the vessel and a tubular conduit forming atight closure for the space between them provided with groups ofdiverging spray or jet apertures directed toward the vessel and anaperture and a closure therefor opposite each group of jet. aperturesfor permitting access thereto from the exterior.

2. A container comprising a metallic vessel provided on its interiorsurface with a glass enamel coating fused thereon, said vessel havingone end flanged to receive a cover, an exterior metallic shell spacedfrom the outer side of the vessel and terminating short of said flange,a metallic ring-shaped tube having its inner peripheral wall portionunited with the. material of the vessel by welding and its otherperipheral wall portion similarly united with the metallic shell wherebyto form a complete closure for the space between the vessel and upperend of the shell, said tubular ring having jet apertures leading fromits interior to the space between the vessel and shell and also having aremovable closure for permitting access thereto from the exterior of thevessel.

3. An upright container comprising a metallic vessel, a metallic jacketor shell surrounding and spaced from the vessel and having its upper endterminating short of that of the vessel, :1 n'ietallic tubular ringsurrounding the vessel and bridging the space between the latter and theupper end of the jacket, said tubular ring having its inner and outerperipheral portions directly welded to the vessel and jacketrespectively, whereby the ring forms a complete closure for the spacebetween said vessel and jacket, said tubular ring having a plurality ofdischarge apertures leading to said space and a removable closure forthe tubular ring permitting access thereto from the exterior of thevessel.
